【考案の詳細な説明】
この考案は、プレススルーパツクの裏貼りシー
トに関する。[Detailed description of the invention] This invention relates to a backing sheet for a press-through pack.
プレススルーパツクは、第２図に示すように、
収納体１に多数のポケツト部２を設け、この中に
錠剤Ｔなどを収納し、ポケツト部２の外側に裏貼
りシート１０を接着して密封したものであつて、
開封する場合には、ポケツト部２の外側から指で
押圧して、錠剤Ｔで裏貼りシート１０を突き破
り、錠剤を取り出すようにしてある。 The press-through pack, as shown in Figure 2,
A storage body 1 is provided with a large number of pockets 2, in which tablets T, etc. are stored, and a backing sheet 10 is adhered to the outside of the pockets 2 to seal the pockets.
When opening the package, the tablet T is pressed with a finger from the outside of the pocket part 2 to pierce the backing sheet 10 and take out the tablet.
ところで、このような裏貼りシート１０は、通
常厚さ20μ程度のアルミニウム箔を基材として、
その一面にヒートシール層を設け、他面に印刷層
及び表面樹脂層を設けたものであるが、この印刷
層は、アルミニウム箔の艶面に形成されているの
で、艶面の高反射性によつて印刷された文字、図
形などの極めて判読し難くなる欠点がある。 By the way, such a backing sheet 10 is usually made of aluminum foil with a thickness of about 20 μm as a base material.
A heat-sealing layer is provided on one side, and a printing layer and a surface resin layer are provided on the other side. Since this printing layer is formed on the glossy surface of the aluminum foil, the glossy surface has high reflectivity. This has the disadvantage that printed characters, figures, etc. are extremely difficult to read.
この考案は、上記の欠点を解消し、アルミニウ
ム箔に印刷された文字などが明瞭に観取できるよ
うにした裏貼りシートを提供することが目的であ
る。 The purpose of this invention is to provide a backing sheet that eliminates the above-mentioned drawbacks and allows characters printed on aluminum foil to be clearly seen.
上記の目的を達成するため、この考案において
は、表面樹脂層を形成する樹脂中に、平均粒径が
１〜10μの充填剤を樹脂分に対して0.1〜５重量％
混入したのである。 In order to achieve the above object, in this invention, a filler with an average particle size of 1 to 10μ is added to the resin forming the surface resin layer in an amount of 0.1 to 5% by weight based on the resin content.
It was mixed in.
このような充填剤を混入することによつて、表
面樹脂層表面に現れた微細な凹凸や充填剤そのも
のにより、入射光、反射光共に散乱させることが
できるので、アルミニウム箔の艶面に印刷された
文字等を明瞭に観取することができるようになる
のである。 By mixing such a filler, both incident light and reflected light can be scattered by the fine irregularities that appear on the surface of the surface resin layer and the filler itself, so it is possible to scatter both incident and reflected light. This makes it possible to clearly see written characters, etc.
以下、この考案の実施例は添付図面に基いて説
明する。 Embodiments of this invention will be described below with reference to the accompanying drawings.
第１図に示すように、裏貼りシート１０は、ア
ルミニウム箔１１の一面にヒートシール層１２、
他面に印刷層１３及び表面樹脂層１４を設けたも
のである。 As shown in FIG. 1, the backing sheet 10 includes a heat seal layer 12 on one side of an aluminum foil 11,
A printed layer 13 and a surface resin layer 14 are provided on the other side.
上記アルミニウム箔１１は、硬質、軟質いずれ
でもよいが、内容物の保護及びそれを取り出す際
の突き破り性からみて15〜30μの厚みが望まし
い。即ち、15μ以下ではピンホールが生じ易く、
30μを超えると突き破り性が悪くなるからであ
る。 The aluminum foil 11 may be either hard or soft, but a thickness of 15 to 30 μm is desirable in terms of protection of the contents and breakability when taking out the contents. In other words, if the thickness is less than 15μ, pinholes are likely to occur.
This is because if the thickness exceeds 30 μ, the penetration property deteriorates.
上記ヒートシール層１２は、塩化ビニル又は酢
酸ビニル系共重合体、或は塩素化ポリプロピレン
等を主成分とする通常の熱可塑性接着剤から成つ
ている。 The heat seal layer 12 is made of a conventional thermoplastic adhesive whose main component is vinyl chloride or vinyl acetate copolymer, chlorinated polypropylene, or the like.
上記表面樹脂層１４は、例えばニトロセルロー
ス、アクリル樹脂、エポキシ樹脂又はこれらの混
合樹脂などを主成分にし、これに平均粒径が１〜
10μの充填剤を0.1〜５重量％、好ましくは0.5〜
３重量％混入したものである。この充填剤として
は、酸化硅素や二酸化チタン、亜鉛華、炭酸カル
シウム、アルミナホワイトなどの白色系が好まし
いが、これに限らない。また着色顔料を用いるこ
ともできる。 The surface resin layer 14 is mainly composed of, for example, nitrocellulose, acrylic resin, epoxy resin, or a mixed resin thereof, and has particles having an average particle size of 1 to 1.
10μ filler from 0.1 to 5% by weight, preferably from 0.5 to 5% by weight
It contains 3% by weight. The filler is preferably a white filler such as silicon oxide, titanium dioxide, zinc white, calcium carbonate, or alumina white, but is not limited thereto. Colored pigments can also be used.
上記充填剤の平均粒径は、1μより小さいと艶
消し効果が充分ではなく、10μより大きいと樹脂
層１４の表面の凹凸が大きすぎて滑り性が悪くな
り、プレススルーパツクの製造工程中の作業性に
問題が生じる。 If the average particle size of the filler is smaller than 1μ, the matting effect will not be sufficient, and if it is larger than 10μ, the surface of the resin layer 14 will be too uneven, resulting in poor slipperiness, which may cause problems during the press-through pack manufacturing process. Problems arise in workability.
また、混入量は、0.1重量％より少ないと、艶
消し感が現れず、５重量％よりも多いと印刷が見
え難くなる。 Furthermore, if the amount is less than 0.1% by weight, no matte feeling will appear, and if it is more than 5% by weight, the printing will be difficult to see.
さらに、樹脂層１４の表面滑り性をよくするた
め低分子ポリエチレンワツクスなどの添加剤を混
入したり、メラミンなどの硬化剤を加えることが
できる。このようにして、充填剤などを混入した
樹脂を0.5〜5.0ｇ／m2好ましくは0.5〜2.0ｇ／m2
塗布することにより表面樹脂層１４を形成する。
この場合、塗布量が0.5ｇ／m2以下であると、光
の干渉縞が生じ、5.0ｇ／m2以上塗布してもさほ
ど効果をあげることができないだけでなく、かえ
つて塗布量が多すぎて、印刷が見難くなることも
ある。 Furthermore, in order to improve the surface slipperiness of the resin layer 14, additives such as low-molecular polyethylene wax or the like or a hardening agent such as melamine may be added. In this way, the resin mixed with fillers etc. is 0.5 to 5.0 g/m 2 , preferably 0.5 to 2.0 g/m 2
A surface resin layer 14 is formed by coating.
In this case, if the coating amount is less than 0.5 g/m 2 , optical interference fringes will occur, and if the coating amount is 5.0 g/m 2 or more, not only will it not be very effective, but the coating amount will be too large. This can make the print difficult to see.
なお、第３図に示すように、まずアルミニウム
掃く１１に表面樹脂層１４を形成した後、印刷層
１３を設けてもよい。 Incidentally, as shown in FIG. 3, the printed layer 13 may be provided after first forming the surface resin layer 14 on the aluminum cover 11.
以下、さらに詳細な実験例と比較例を挙げる。 More detailed experimental examples and comparative examples are given below.
20μの厚さの片艶硬質アルミニウム箔の艶面に
簡単な文字を印刷し、その上に表面樹脂層を形成
した。
Simple characters were printed on the glossy surface of a 20μ thick single-glazed hard aluminum foil, and a surface resin layer was formed on top of it.
この表面樹脂層は、ニトロセルロース樹脂とア
クリル樹脂及びメラミン樹脂の混合物を主成分と
し、これに平均粒径3μの酸化硅素を樹脂固形分
に対して約3.5重量％混入し、0.5ｇ／m2塗布した
ものである。 This surface resin layer is mainly composed of a mixture of nitrocellulose resin, acrylic resin, and melamine resin, and silicon oxide with an average particle size of 3 μm is mixed therein in an amount of about 3.5% by weight based on the solid content of the resin . It is coated.
塗布乾燥後、その表面を目視で観察したとこ
ろ、ギラギラした光沢がなくなり、適度の艶消し
面になつており、また光の干渉縞も発生せず、印
刷が識別し易くなつていた。 After coating and drying, the surface was visually observed, and it was found that the glittering gloss had disappeared and the surface had become a moderately matte surface, and no light interference fringes had occurred, making the printing easy to identify.
実験例と同じように印刷したアルミニウム箔
に、同じ充填剤を同量混合した同じ樹脂を0.3
ｇ／m2塗布して表面樹脂層を形成したところ、艶
消し効果が充分でなく、また光の干渉縞が発生
し、印刷が極めて識別し難しなつていた。
0.3 of the same resin mixed with the same amount of the same filler was applied to aluminum foil printed in the same way as in the experimental example.
When a surface resin layer was formed by applying g/m 2 , the matting effect was not sufficient and optical interference fringes were generated, making printing extremely difficult to distinguish.
この考案によれば、以上のように、表面樹脂層
を形成する樹脂中に細い粒子から成る充填剤を混
入したので、この層の表面に細い凹凸が現れて乱
反射を起こさせ、さらに光を吸収するので、その
面が艶消しになつて、基材のアルミニウム箔の艶
面による高反射を抑制し、印刷された文字等が非
常に見易くなる効果がある。 According to this invention, as described above, a filler consisting of thin particles is mixed into the resin that forms the surface resin layer, so that thin irregularities appear on the surface of this layer, causing diffuse reflection and further absorbing light. Therefore, the surface becomes matte, which suppresses the high reflection caused by the glossy surface of the aluminum foil as the base material, and has the effect of making printed characters etc. very easy to see.
